Gaga started the the halftime show with a medley of patriotic songs performed on top of the NRG Stadium roof in Houston, Texas, with a fleet of lit-up drones hovering above. She then lept into the stadium with a harnass and continued with some of her most familiar songs, including “Poker Face,” “Telephone,” “Bad Romance,” “Paparazzi” and "Born This Way."

Gaga had said she hopes her Super Bowl show will celebrate "inclusion" and the "spirit of equality" during a time of national division.

"This performance is for everyone. I want to, more than anything, create a moment that everyone that's watching will never forget," she said in a press conference Thursday in Houston.

When Gaga debuted in 2008, her sound was a mix of electronic, dance and pop sounds, including the hits "Poker Face" and "Just Dance." Her latest album though, "Joanne," delves into country and acoustic rock territory.

The 30-year-old singer, who sang the national anthem at last year's Super Bowl, was nominated for the best original song Oscar last year and won a Golden Globe for her role on the FX series "American Horror Story." Gaga said she considers being asked to be the halftime headliner is due to her fans, affectionately known as "little monsters."

"Essentially, that kid that couldn't get a seat at the cool kids table and that kid who was kicked out of the house because his mom and dad didn't accept him for who he was? That kid is going to have the stage for 13 minutes," she said. "And I'm excited to give it to them."

Gaga wouldn't reveal whom she's rooting for in the showdown between the New England Patriots and Atlanta Falcons. "I'm going to keep that one to myself," she said.
